The homeowner armed himself, went to the garage because he heard noises there, encountered Espino, and shot him once, police said.

Espino was critically injured but he was upgraded to stable condition late Monday afternoon. The homeowner wouldn’t go on camera but said, “The whole thing scared the hell out of me.”

Police said the homeowner was taken to the police station, questioned, and released. He was fully cooperative with detectives.

For now, police said it appears the homeowner was protecting life and property and was in his legal right to use deadly force. But police also said the investigation remains open and they hope to speak with the suspected burglar, who is hospitalized.

Investigators said they will forward their findings to the district attorney’s office for a full review of the homeowner’s actions and possible charges against Espino.
